detailed description

The composition and working principle of an automatic vending machine alarm system for preventing violent damage and technical unlocking will be further introduced below in conjunction with the accompanying drawings.

As shown in Figure 1, a structural block diagram of an automatic vending machine alarm system for preventing violent damage and technical unlocking, an automatic vending machine alarm system for preventing violent damage and technical unlocking includes an on-site central control terminal and an upper computer remote monitoring terminal, The on-site central control terminal includes a signal acquisition module, a main control center module, a SIM module, and an on-site alarm module, and the main control center module includes a theft signal acquisition module and a wireless module.

As shown in Figure 2, a schematic diagram of the installation of an automatic vending machine alarm system for preventing violent damage and technical unlocking.

The signal acquisition module uses a vibration sensor array, a magnetic switch, and a camera.

The vibration sensor array uses a high-sensitivity vibration sensor SW-1801P. Four vibration sensors 9 are respectively installed on the inner four corners of the glass panel of the vending machine front panel 1 to form a vibration sensor array, and are connected to the sensor arbitration mechanism 6 of the main control center 5 . If you want to further improve the accuracy of the collected signal, you can expand more sensors to form a sensor array, the more the number of sensors, the more accurate.

The magnetic switch is used to detect whether the protective door of the automatic vending machine is opened. The magnetic switch consists of a sensor 10 and a soft magnet 11 attached to the adjacent positions of the front panel 1 and the right side panel 2 of the vending machine respectively, and is connected to the identification module 7 of the main control center 5 . When the sensor 10 and the soft magnet 11 are close, the sensor 10 senses the presence of a magnetic field, indicating that the door is in a closed state. When the sensor 10 is separated from the soft magnet 11, the sensor 10 cannot sense the existence of the magnetic field, indicating that the door is opened.

The camera module adopts a camera with a CSI interface for taking on-site photos. The camera 12 is directly connected to the main control center 5 through the CSI interface, and when the main control center receives a camera instruction from the host computer, the camera starts to take pictures of the scene.

The main control center module is Raspberry Pi 3 generation B+. It has the characteristics of strong processing ability, fast operation speed, ultra-low power consumption and abundant resources on the chip. The main control center module includes a theft signal identification module and a wireless module.

The theft signal identification module includes a vibration sensor arbitration mechanism 6 and an identity identification module 7 . Vibration sensor arbitration mechanism 6 is used to identify whether there is violent damage and theft. Sensor arbitration mechanism 6 analyzes the collected vibration signals according to the different weighted values of the vibration sensors at different positions. When the vibration signals collected by these sensor arrays are weighted The value of exceeds the warning value, and the sensor arbitration mechanism 6 judges it as violent sabotage and theft. The identity recognition module 7 is used to identify whether there is a technology unlocking theft, and the identity recognition module 7 identifies whether there is the technology unlocking theft by detecting whether the unlocker has passed identity authentication. When receiving the signal that the door is in an open state, the identity recognition module 7 starts to work. If the identity authentication fails, it is judged as a technology unlocking theft.

The wireless module 8 is used to realize the communication between the main control center and the remote monitoring end of the upper computer, and the main control center sends real-time data to the remote monitoring end of the upper computer through the wireless module 8 and accepts specified commands of the upper computer.

4. The SIM module 15 is used to make calls to background management staff. After the main control center received the alarm signal, the main control center started the SIM module 15 for dialing the phone of the background manager.

The on-site alarm module includes a sound system and an alarm flashing light, which can perform on-site alarming flashing light alarm and voice warning at the same time.

The alarm flash is controlled by a relay. First, combine the relay 13 and the alarm flash 14, and then lead a signal line from the relay 13 to the main control center 5 of the Raspberry Pi. The main control center 5 can be controlled by this signal line The on-off of relay 13 circuit. When receiving the alarm instruction sent by the main control center, the relay 13 circuit is connected, and the alarm flashlight 14 starts to work. When the alarm instruction is not received, the relay module 13 circuit is always disconnected, and the alarm flashlight 14 does not work.

The sound box 16 can be directly inserted into the audio interface of the main control center 5 through the connector of the wire, and the hardware of the main control center 5 is integrated with a sound card, and the sound card driver is self-contained on the system. When receiving the alarm command sent by the main control center, the speaker 16 starts to play the recorded voice.

The remote monitoring terminal of the upper computer includes a mobile phone terminal and a PC terminal, which are used for answering calls, receiving on-site information and performing remote management, so as to realize remote control of the vending machine. When the host computer receives the alarm command, the background management personnel can retrieve the on-site pictures through the host computer to judge whether there is a thief committing theft. If it is a false alarm, the host computer can send a stop alarm command to the main control center. If it is true that the thief is stealing, you can call to the scene through the host computer, or take other measures to stop the theft in time and arrest the thief.

Specific application examples

A work flow diagram of an automatic vending machine alarm system for preventing violent damage and technical unlocking is shown in Figure 3:

When the system starts to work, the whole system is initialized, and the four threads are all in the initialization state. The workflow of each thread is as follows:

Thread 1: Use the magnetic switch to detect whether the door is open. If it detects that the door is not open, continue to detect. If it detects that the door has been opened, it will proceed to the next step of identification. If the identity has passed the authentication, it will return to the state of door opening detection. If the identity If the authentication is not passed, an alarm signal will be issued.

Thread 2: Scan the vibration sensor, and send the vibration signal to the sensor arbitration mechanism for analysis. If the sensor is not enabled, it means that the vending machine has not been violently damaged, and returns to the vibration sensor scanning state. If the sensor is enabled, it is proved that violent destruction exists, and an alarm signal is sent.

After the main control center receives the alarm signal from line 1 or 2, it immediately starts the alarm command, the SIM module starts to call the background staff, activates the on-site alarm device, the speaker starts to play the voice warning, the alarm flasher starts to alarm, and at the same time drives the wireless module to The upper computer sends an alarm message.

Thread 3: Waiting for instructions from the host computer. When the upper computer receives the alarm information, it sends an instruction to the main control center through the wireless module to retrieve the scene image, and the thread 3 sends a photographing instruction to the line 4 after receiving the instruction.

Thread 4: Thread 4 waits for the camera command sent by Thread 3. When thread 4 receives the camera instruction sent by thread 3, it starts the camera to take pictures and uploads them to the host computer through the wireless module.

When the host computer receives the alarm command, the background management personnel can retrieve the on-site pictures through the host computer to further confirm whether there is a theft. If it is a false alarm, the host computer can send a stop alarm command to the main control center. If there are indeed thieves who are stealing, you can call the scene through the host computer, or take other measures to stop the theft in time and arrest the thieves.
